- A. Valvular aortic stenosis
- B. Hypertrophic obstructive cardiomyopathy
- C. Valvular pulmonic stenosis
- D. Mitral valve prolapse

A nurse assesses a client who is recovering from a myocardial infarction. The client’s pulmonary artery pressure reading is 25/12 mm Hg. Which action should the nurse take first?
- A. Compare the results with previous pulmonary artery pressure readings.
- B. Increase the intravenous fluid rate because these readings are low.
- C. Immediately notify the health care provider of the elevated pressures.
- D. Document the finding in the client’s chart as the only action.
Correct Answer: A
Rationale: Comparing the current pulmonary artery pressure readings with previous ones helps determine if the values are stable or changing, which guides further intervention.
Examples of cyanotic heart disease include:
- A. Ebstein's anomaly
- B. Pulmonary stenosis
- C. Coarctation of aorta
- D. Hypoplastic left heart syndrome
Correct Answer: D
Rationale: Hypoplastic left heart syndrome is a form of cyanotic heart disease. Ebstein's anomaly and pulmonary stenosis can also cause cyanosis, but coarctation of the aorta typically does not.
One of the following is a characteristic physical finding in patients with an ASD
- A. a right precordial bulge
- B. a fixed splitting of the second heart sound
- C. a systolic ejection heart murmur
- D. a short, mild left mid-diastolic murmur
Correct Answer: B
Rationale: Fixed splitting of the second heart sound is a hallmark of an atrial septal defect.
Regarding immunoglobins:
- A. IgG2 concentrations increase with age
- B. IgD is useful in mediating the late features of allergic reactions
- C. IgG2 subclass deficiency is associated with IgA deficiency
- D. IgM is complement-fixing antibody
Correct Answer: D
Rationale: IgM is complement-fixing antibody
A child born with Trisomy 21 should be evaluated for which associated cardiac manifestation?
- A. Systemic hypertension
- B. Congenital heart defect
- C. Hyperlipidemia
- D. Cardiomyopathy
Correct Answer: B
Rationale: Children with Trisomy 21 (Down syndrome) have a high incidence of congenital heart defects, such as atrioventricular septal defects, and should be evaluated for these conditions.
